Signals on gantries at intersections

SR 228

After some searching I noticed there isn't a thread for this.
https://goo.gl/cBsMiR This is a set of all kinds of PV signals, which are mostly 3M, on a gantry, what a beauty.

One such example in San Jose, CA... https://goo.gl/maps/rC7ZSP1oWar.

This is the Taylor Street SPUI with CA-87.  I was about the post a GMSV link for the Bay Bridge metering lights until I saw the OP specifically ask for examples at intersections.

There's this one right in the center of the I-270/MD-189 SPUI in Rockville:

And this might not be exactly what the OP had in mind, but there's a combination of signs and signals at the north end of I-180 in Cheyenne:

Here's some signals on a gantry in Dubuque, IA.

Iowa seems to be quicker to switch to gantries for large intersections compared to other states.  Other Iowa examples:

* Coral Ridge Avenue at Holiday Road in Coralville

* US 6 at Adventureland Drive near Des Moines

* US 6 at 34th Street near Des Moines



In Illinois IDOT District 3 will mount signals on BGS gantries for roads that have interchanges with I-80:
* NB Ridge Road at the EB I-80 ramps

* SB Ridge Road at the I-80 WB ramps

* NB IL 23 at the I-80 EB ramps

* SB IL 23 at the WB I-80 ramps


This also happens frequently with overhead SPUI's (freeway goes under the cross road; for the opposite the signals seem to frequently be hung on the overpass) and for intersections near railroad crossings:

SPUI examples:
* MO 94 at I-70 in St. Charles, MO

*MO 141 at Big Bend Road near St. Louis

*Rosa Parks Way at US 77 in Lincoln, NE

*NE 2 at US 77 in Lincoln, NE

Railroad crossing examples:
* SB Wood Dale Road at IL 19

* Wilke Road at US 14

* IL 22 at IL 43

* Pontoon Road at Missouri Avenue in Granite City, IL

Here's one along I-270 in Maryland.  Think they have done this for decades at this SPUI.

Orange Blossom Trail between FL 528 and Oakridge Road has many of them thanks to a bureaucracy called the South Trail Board who was created to beautify the trail during the 90's.  They agreed that this was a step in the clean up of the red light district that plagued the county, by saying that they taxed the businesses to fund these ugly green gantries that cost over 300 grand to install.

I work along that section of "The Trail" ( no not selling meth or my body) I hate the look of the gantry traffic lights.  The gantries continue up to i4. The look is very 1990.

Interestingly  the biggest intersection at Sand Lake Road has a guy wire 4 box, not gantries

Wenatchee Washington has one at the intersection of US 2/SR 28.

One of the stranger uses I've seen of a gantry for signals is on Stringfellow Road at Poplar Tree Road in Chantilly, Virginia. You may have to click into Street View to see this because the Google Maps app won't let me get a link directly from the Street View screen.

When you drive through here, the gantry seems huge for the location.

There are two gantry-mounted signal intersections I know of currently in Maine. The first one is along ME 9 (Western Avenue) at Gorham Road in South Portland, and the second along ME 22 (County Road) at Spring Street in Westbrook. There used to be another one in the same town at the west end of the Westbrook Arterial, but it was replaced some years ago. Here is the street view of the gantry from before it was taken down.

As for other examples, here are a handful I've come across in my travels...

I asked Orange County about that one, and they said because of the geometric of that intersection it was impossible to support a gantry across any of that intersection.  It is one of the widest intersections around, and thank God for that or we would have one more ugly gantry to look at.

Even when Walmart opened up, the South Trail Board still had power to install ugly green partial gantries instead of just going regular mast arm or doing a span wire.  Even in Kissimmee where they reconfigured US 192 at both JYP and at Main Street, they were allowed to go with brown mast arms rather than recreate the span wire design of 1989 when the original signals were erected from Oak Street to Hoagland Blvd. when FDOT added a third lane each way from its previous 4 lane.  Here that idiot Board wants to keep forever the look of the grene and any new signals put up will have to be a green bracket or trusses.

Wow Caltrans not using a mast arm set up!  Also only two signal heads per direction?   That is odd considering California does what Illinois does and mounts side signal heads in addition to the MUTCD overheads.

Edit: Now I see them, as they are behind the image in the caption.

I kind of like them for the area. I just wish they would install the signals with the bottom aligned to the bottom of the gantry and add a near side signal to each of them. They've aged better then the pink sidewalks.

I think there is a proposal to continue it beyond I-4, they've given OBT near downtown a very similar treatment (although not done quite as well, they didn't bury all the powerlines and mounted the street lights to the power poles, often with mismatched arms with no rhyme or reason). They have a 1.5 mile gap now.

Alum Creek Drive at Groveport Rd, Columbus, OH. This one is a little weird because it's also a superstreet with a grade-separated bypass for cross road through traffic.

From Nevada, all in the Las Vegas area:

Older installations installed due to Las Vegas Blvd North running on a sharp diagonal, and all but the last being a simple truss-style:Newer installations are all bulky monotubes:
Note that these are all installed on current/former state highways, or at interchanges with state highways, so they seem to be an NDOT thing–especially at SPUIs. By comparison, some SPUI intersections along the 215 beltway, designed by Clark County, instead use two separate mast arms at the center of the bridge (example: Green Valley Pkwy & I-215 ramps, Henderson).

    Still a bit odd for them to not use a signal side-mounted on (in this case) the gantry. California is mental about signal placement, so to see them only using one side-mounted signal is odd. Especially since it's a stop line signal, and those have traditionally been extra-credit (although have become ubiquitous lately).

    All told, the only side-mounted signals you really see at SPUIs are those mounted on their own exclusive poles, usually on the near or far side of the intersection. That said, here's a couple examples of signals being mounted on or near the signal gantry: Tucson, AZ; Langley, BC (a rare monotube signal gantry -- BC rarely utilises this).

    There's a section of Omaha that likes using giant gantries mounted diagonally over their larger intersections. 
    This is similar to the Iowa ones mentioned upthread.  https://goo.gl/maps/oay7FrJXkDC2

    Someone else mentioned that IDOT District 3 will mount signal heads on sign gantries at the grade intersections with freeway interchanges.  Here's another one at I-57 and IL-17 in Kankakee https://goo.gl/maps/NfHSRgbBeSA2

    In Utah, every SPUI with the freeway under the cross-street mounts all the lights onto one big monotube, and there are at least 11 of these. There are also cases like this and this, which are a traffic light and BGS rolled into one.

    There's also this. It's a weird intersection, and it looks like the plan is to convert it into a full interchange at some point.

    I like the concrete pavement on OBT north of I 4 up to about the Parliament House... But signal timing sucks, which is normal for Orange County

    I didn't realize until you posted this, but all those Nevada SPUI intersections I posted also follow this pattern. No pole-mounted signal heads on the main mast/monotube poles (but always a near-side pole mount for the through movement and a way-far-side pole mount for the left turn movement).
